A lot of people are planning trips this time of year, so here's a bumped-up reminder. Especially if you are going to be climbing, you'll want travel medical insurance if you leave Korea this summer. Korean National Insurance will not cover you abroad, your home country insurance may not cover you if you are no longer residing there, and if you are traveling in less developed countries, you may need/want to evacuate or visit a 9001 certified "foreign" hospital which will probably want insurance or a helfty deposit up-front.
After decades of climbing and traveling I've experienced and heard of some horror stories-- insurance can be a real lifesaver and provide incredible peace of mind.
I use
Medex, but there are many other options if you google.
